I find about a squirt and a half in Shemp's food does quite well. I can't afford Science Diet and have to use Wal-Mart brand, but the addition makes it quite palitible (sp?) to Shemp. I now have a question, does anyone have a huge problem with fleas? One day no fleas, the next, 1.e500. They seem to be tapering off since I got the tralier sprayed, but every flea that was not killed found Shemp. I have also heard that a ferret/cat owner had a situation where his two ferrets had tons of fleas, where the cat had few to none. Any comments? Drake [Posted in FML issue 0619]
